BACKGROUND: We postulate that a delay in the implementation of hepatic arterial embolization for traumatic liver injury patients will negatively affect patient prognosis. Our work also seeks to identify factors related to the mortality rate among traumatic liver injury patients. METHODS: From January 2008 to April 2014, patients who had been admitted to the emergency room, were subsequently diagnosed with traumatic liver injury, and later underwent hepatic arterial embolization were included in this retrospective study. RESULTS: Of the 149 patients that underwent hepatic arterial embolization, 86 had the procedure due to traumatic liver injury. Excluding the 3 patients that were admitted to the hospital before procedure, the remaining 83 patients were used as subjects for the study. The average time between emergency room arrival and incidence of procedure was 164 min for the survival group and 132 min for the non-survival group; this was not statistically significant (p = 0.170). The average time to intervention was 182 min for the hemodynamically stable group, and 149 min for the hemodynamically unstable group, the latter having a significantly shorter wait time (p = 0.047). Of the factors related to the mortality rate, the odds ratio of the Glasgow Coma Score (GCS) was 18.48 (p < 0.001), and that of albumin level was 0.368 (p = 0.006). CONCLUSIONS: In analyzing the correlation between mortality rate and the time from patient admission to arrival for hepatic arterial embolization, there was no statistical significance observed. Of the factors related to the mortality rate, GCS and albumin level may be used as prognostic factors in traumatic liver injury.

BACKGROUND: Head lift (HL) for 5 seconds and tongue depressor (TD) test have been used for diagnosis of the residual block after using the nondepolarizing muscle relaxants. We investigated validity and reliability of HL, TD, and both of them (HLTD). METHODS: Four-hundred-thirteen patients were enrolled in this study. Neuromuscular blockade was maintained with rocuronium and reversed with pyridostigmine and glycopyrrolate. TOF ratio was quantified by acceleromyograph in the recovery room. HL and TD test were performed in the patients who could respond to verbal command of the investigator. We analyzed the sensitivity, specificity, positive and negative predictive value, positive and negative likelihood ratio, area under the cure (AUC) from ROC analysis and kappa statistics. RESULTS: Prevalences of residual block were 13%, 32% and 78% at 0.7, 0.9 and 1.0 of TOF ratio cutoff value, respectively. Specificity was good for HL (79.7-86.8%), TD (94.2-97.8%) and HLTD (77.8-85.7%), but sensitivity was not. Positive predictive value was higher in TD than HL and HLTD, and negative predictive value was similar among them. Positive and negative likelihood ratio was higher in TD than HL and HLTD. AUC had no difference among HL, TD and LTD. Kappa statistics were showed minimal or moderate relationship between clinical test and train of four responses. CONCLUSIONS: We concluded that HL, TD and HLTD were not good tools for diagnosis of the residual block in a view of validity and reliability.

Zoletil is a non-opioid, non-barbiturate animal anesthetic and proprietary combination of two drugs, a dissociative anesthetic drug, tiletamine, with the benzodiazepine anxiolytic drug, zolazepam. Zoletil has greater potency than ketamine. Zoletil is abused for recreational purposes, especially by people with easy access to medicine. However, in Korea, it is available over-the-counter. Here we report on a case of an 83-year-old woman who received injection of seven vials of "Zoletil 50" by her daughter and presented with an altered mental change. Her mental state was stupor and vital sign was hypotension, bradycardia. Her blood tests indicated metabolic and respiratory acidosis and hyperkalemia. She was treated with intravenous naloxone and flumazenil but was not responsive. She was admitted to the ICU and treated with supportive therapy. Her mental state showed transient recovery, however, her clinical manifestation worsened and she expired.

OBJECTIVE: The aim of this study was to identify diffrentially regulated genes after the treatment of fluoxetine in rat C6 glioma cells using cDNA microarray chip techniques and real-time RT-PCR. METHODS: Cells were incubated for 24 hours, and for 72 hours with or without 10 uM fluoxetine. Total RNAs extracted from cells were reversely transcribed to cDNA. These cDNA were used to carry out cDNA microarray chip. A part of the up-/down-regulated genes in cDNA microarray result were confirmed by real-time RT-PCR. RESULTS: 1) Genes in fluoxetinetreated cells for 72 hours (chronic treatment) were more regulated than that in fluoxetine-treated cells for 24 hours (acute treatment). 2) The expression level of Gs gene in fluoxetine-treated cells for 24 hours hardly altered, but that of Gs in fluoxetine-treated cells for 72 hours significantly increased. The expression of Gi2 also decreased in 72 hours in relation to 24 hours after the administration of fluoxetine. 3) The expression level of NCAM140 gene in fluoxetine-treated cells was higher than that in control cells. CONCLUSION: We identified genes (Gs, Gi2 and NCAM140) related to neural plasticity and intracellular signal transduction cascade from our result. This implies that fluoxetine may inhibit atrophy or death of impaired neural cells by promoting neurite outgrowth.

OBJECTIVES: Most of the mechanisms reported for antidepressant drugs are the enhancement of neurite outgrowth and neuronal survival in the rat hippocampus. Neural cell adhesion molecule 140(NCAM140) has been implicated as having a role in cell-cell adhesion, neurite outgrowth, and synaptic plasticity. In this report, we have performed to elucidate a correlation among chronic antidepressant treatments, NCAM140 expression, and activation of phosphorylated cyclicAMP responsive element binding protein(pCREB) which is a downstream molecule of NCAM140-mediated intracellular signaling pathway in the rat hippocampus. METHODS: Fluoxetine(10mg/kg) was injected acutely(daily injection for 5days) or chronically(daily injection for 14days) in adult rats. RNA and protein were extracted from the rat hippocampus, respectively. Real-time RTPCR was performed to analyze the expression pattern of NCAM140 gene and western blot analyses for the activation of the phosphorylation ratio of CREB. RESULTS: Chronic fluoxetine treatments increased NCAM140 expression 1.3 times higher than control in rat hippocampus. pCREB immunoreactivity in the rat hippocampus with chronic fluoxetine treatment was increased 4.0 times higher than that of control. CONCLUSION: Chronic fluoxetine treatment increased NCAM140 expression and pCREB activity in the rat hippo-campus. Our data suggest that NCAM140 and pCREB may play a role in the clinical efficacy of antidepressants promoting the neurite outgrowth and neuronal survival.

PURPOSE: A stylet aids intubation as a glottis by changing and maintaining the bending inside the endotracheal tube and is used as an auxiliary device in intubation. The aim of this experimental study is to evaluate resistance differences among endotracheal tube sizes and the usefulness of lubricant for stylet removal. METHODS: Depending on endotracheal tube size and lubricant use status, the subjects were divided into the control (n=10, each 7 tube sizes), lidocaine gel (n=70), and saline groups (n=70). Using a tensile strength meter, the work and the peak withdrawal force consumed for retracting a stylet were measured. RESULTS: When the work dependent on the endotracheal tube size and stylet coating was compared, significantly less work was consumed for 6.0-, 6.5-, 7.0-, 8.0-, 8.5 mm stylet group coated with lidocaine gel (p=0.029, p=0.002, p=0.001, p=0.001, p<0.001, p<0.001) or 6.0-, 6.5-, 8.0-, 8.5 mm stylets coated with saline compared to the control group (p=0.002, p<0.001, p<0.001, and p<0.001). In comparison of the peak withdrawal force dependent on the endotracheal tube size and stylet coating, significantly less peak withdrawal force was consumed for the 6.0- or 8.0- mm stylet group coated with lidocaine gel (p=0.004, p<0.001) or 6.0-, 6.5-, 7.5-, or 8.0 mm stylets coated with saline compared to the control group (p=0.025, p=0.001, p=0.008, and p=0.001). CONCLUSION: We found that the effectiveness of lubricant resulted in various sized tubes. Less work was consumed for five tube sizes (6.0-, 6.5-, 7.0-, 8.0-, 8.5 mm) in lidocaine gel groups and four tube sizes (6.0-, 6.5-, 8.0-, 8.5 mm) in saline groups. Less peak withdrawal force was consumed for two tube sizes (6.0-, 8.0 mm) in lidocaine gel groups and four tube sizes (6.0-, 6.5-, 7.5-, 8.0 mm) in saline groups.

Jejunal infarction as a complication of acute pancreatitis is not common and can not be well recognized. This jejunal infarction usually arises from the venous thrombosis rather than arterial thrombosis. Jejunal infarction results in bowel perforation or stenosis according to its extension of injury and progression rate. Pathologic findings of the involved jejunum show a segmental transmural infarction and mesenteric venous thrombotic occlusions. Early diagnosis should be made for better prognosis. We report a patient with jejunal infarction resulting perforation due to acute pancreatitis, in which the initial presenting symptoms were hematemesis and abdominal distention.

OBJECTIVE: Our aim was to evaluate the changes in blood glucose control and lipid profiles after 2-months of smoking cessation in healthy males. METHODS: Smoking abstinence was evaluated through self-report and urine cotinine levels. 12 individuals who succeeded in quitting smoking were analyzed. Fasting values of glucose and insulin were used to estimate the beta-cell activity and insulin resistance was evaluated using the Homeostasis Model Assessment (HOMA) and Quantitative Insulin Sensitivity Check Index (QUICKI). RESULTS: The data showed that the subjects had a significant increase in weight, body mass index and fasting plasma glucose levels after smoking cessation. The HOMA-Insulin Resistance and the HOMA beta-cell function increased significantly (p=0.005, p=0.047 respectively). The QUICKI showed a significant decrease (p=0.005). In addition, the low-density lipoprotein cholesterol levels decreased significantly (p=0.028); however, changes in the high-density lipoprotein cholesterol, the triglyceride and total cholesterol levels were not significant (p=0.284, p=0.445 respectively). CONCLUSION: During the initial stage of smoking abstinence, insulin resistance increased and insulin sensitivity decreased due to elevated body weight and fat composition. Therefore, it is important to educate individuals that stop smoking about the necessity of weight control during smoking cessation programs.
